FREDERICK J. KIESER, OF CHICAGO, ILLINOIS.

TOBACCO-PIPE.

To all whom it may concern Be it known that I, FREDERICK J. Kmsnn, acitizen of the United States, residing in the city of Chicago, county ofCook, and State of Illinois, have invented ,certain new and usefulImprovements in Tbacco-Pipes, of which the following is a specification.

The object of this invention is to provide a pipe which willaccommodate, in proportion to its size, avery large amount oli' tobacco,so as to do away with frequent relilling; which will make it unnecessaryto use the finger or an outside appliance to compress the contents ofthe bowl, after the pipe is lighted, in order to keep it burningproperly; and which will do away with the drawing of the smoke throughthe whole mass of the unburned tobacco in the pipe.

In the drawings Figure 1. is a sectional side elevation of my pipe,showing` the false bottom of the tobacco chamber in depressed position,and showing, in dotted outlines, the upper portion of the bowl in raisedposition; F ig. 2. is a vertical section through the lower portion ofthe tobacco chamber and connected parts, with the false bottom of thechamber in raised position; and Fig. 3. is a top plan view of the bowl.

Referring to the drawings,l an ornamental outer bowl 6 is fastened, byscrews 7, metallic casing 8, consisting of bottom 9, inner verticalcylinder 10 and outer vertical cylinder 11, said cylinders beingseparated by cylindrical well 12. To outer cylinder 11 is connected, onthe outside, boss 13 which is formed with vertical tubular opening 14,and also with stemhole 15, the lower end of which communicates throughsmoke channel 16 with opening 14. rIhis opening 14 widens at its lowerend into chamber 17 which is closed by screwplug 18. On cylinder 10there is mounted between it and cylinder 11, with an easy sliding t,cylinder 19, the upper portion of which is enlarged and tted on theinside with an insulating ring of noncombustible material, such astireclay. The lower edge of cylinder 19 is provided with outer annularflange 61, adapted to engage a stop ring G2 which is threaded into theupper end of cylinder 11. Immediately below ring20, cylinder 19 isprovided in its Specification of Letters Patent.

wall with circular smoke channel 21, communicating with the interior ofcylinder 19 by apertures 22. Immediately below ring 20 there is threadedinto a suitable boss 23, at-- tached to cylinder 19, tube 24 which litswith an easy sliding tit into opening 14, eX- tending downward thereinas tar as cylinder 19 extends downward into well 12, and the interior ofwhich communicates at its upper end, through channel 25, with channel21, while the lower end opens into opening 14, and through itcommunicates with channel 16,. In order that the communication withchannel 16 be not interrupted even when tube 24 is in its lowestposition, opening 14 is enlarged by vertical groove 26 which eX- tendsfrom channel 16 to chamber 17. Gland 27 and packing 28 are provided tosecure airtight connection between tube 24 and the upper end oli'opening 14. Into stemhole 15 is threaded hollow stem 29, provided withmouthpiece'30. In cylinder 10 is slidably mounted false bottom 31,provided wit-lr outer depending flange 32, and inner depending flange33, which latter surrounds opening` 34 in the center of false bottom 31,and cor@ responds to annular boss 35 which projects upward from bot-tom9, surrounding opening 65 in the center thereof. On iange 33 and boss 35are mounted the smaller ends of spiral springs 36 and 37 respectively,the larger ends of which bear against a plate 38, provided with flange39 which extends both upward and downward Jfrom its outer edge. Throughopenings 34 and 65, and through corresponding openings 40 and 41 in thecenter of plate 38 and in the center of the bottom of outer bowl 6,respectively, extends vertical stem 42, provided at its upper end withhorizontal pin 43, adapted to engage with its ends the upper edge offalse bottom 31, and provided at its lower end with knob 44, adapted tobe engaged by the Jfingers of the operator. Annular groove is provided,slightly above knob 44, in stem 42, for engagement by catch 46, for thepurgose of holding the stem 42 in elevated position. Aanother springcatch 47 is provided for the purpose of holding false bottom 31 in theposition shown in Fig. 1. when desired. The top of cylinder 19 is closedby cover ib which is oscillatably held by vertical pivot 4:9; and alsohinged on horizontal rivet so as to be capable both of being swungsidewise around pivot i-Q, and tipped up "ard, with rivet 50 as afulcrum. Catch 51 is pii'ovidcd to lock cover @t8 in position. Itshutter 5i? is attached to the un,- dersido of coter -1-9 by means ofstem 53, to the upper end of which is attached knob 5ft as a handle forthe turning of shutter so as to either bring airholes in shutter 52 intoregister with corresponding airholes 5G in eoyer it), or to shut olfVentilation; as desired. There .is also attached to shutter 52 avertical detlecting wing 5T, extending from the center of the spaceunder shutter with an upward slant of its lower edgeT toward thecircumference of shutter The operation of my device is as fol'- lows:mC-atcb L1G is disengaged from groove #15; and stein 4t2 pulleddownward, by means of knob dit, bringing down with it false bottom 31;and ccnnn'essing spriiigs 3G and 37 until spri L.; catch if? engages theupper edge of false bottoni SE1, locking it in the position shown inFig. 1. Stem 4t2 is thereupon pushed upward again until catch tb againengages groove 4:5, thereby locking stem 112 in the position shown inFig. 1. Cylinder 19 is then pulled upward until flange G1 engagesstopring GQ; cover 18 is opened and the whole space between false bottomB1 and coter t8 iilled with tobacco7 which vis firmly pressed down andthen lighted in the `usual way, whereupon cover 48 is closed withshutter 52 in such position as to gire the desired 1entilation. As thetobacco burns down, cylinder 19 is pushed down from time to time,thereby pushing fresh tobacco from below into thc .tire chambersurrouiuled by ring 20; and packing the burningl tobacco therein intoclose contact with such fresh tobacco. lifter cylinder 19 reaches itslowest position, the same purpose is accomplished by `releasing catchi7, and thereby causing springs 3G and 37 to push the tobacco incylinder' 10 upward until all of it has reached the space surrounded byring 2O where it is consumed by the tire therein. Further upwardmovement of false bottom 3l is prevented by its engagement with pin 4:3.In order to prevent an accumulation of unburned tobacco under the centerof cover 41S (the air suction being mainly around the circumference,through the location of apertures 22) wing is occasionally rotated bymeans of knob 54, thereby pushing the tobacco from the center toward theoutside. Chamber 17 serves for the accumulationyn and the opening closedby screwpiug 1i' for the removal7 of condensation moisture, etc. Ashesare from time to time removed by the opening of cover 48.

It is manifest that stein 4t2, with accessories, may be omitted,inasmuch as false bottom 31 may be pushed down into the position shownin Fig. 1, by the finger of the operator inserted from above; while itsupward moven'ient can easily be limited by pins `projected from theinner side of cyl inder 10l` just below its upper edge; also that falsobottom 31 and springs SSG and 37 may be employed independent of the useof the two part telescoping bowl.

I claim 1. In tobacco-pipes the combination of a bowl having aiirechamber at its upper end, and a smoke exhaust from the circumferenceof the lirechamber, with a cover, and a ver tical rotatable stempenetrating the center of the cover, `Ijnovidcd at its upper end with aknob; and at its lower end with an eccentric wing. substantially as and`for the purpose described.
